Uy v. Public Estates Authority
REVERSALFacts
The Antecedents: Petitioner Elpidio S. Uy (Uy), doing business as Edison Development & Construction (EDC), entered into a contract with respondent Public Estates Authority (PEA) for the Heritage Park Project. Disputes arose concerning claims for equipment rentals on standby, cost of idle manpower, construction of a nursery shade net area, additional hauling distance of topsoil, and mobilization of water trucks. Procedural History: The Construction Industry Arbitration Commission (CIAC) rendered an arbitral award in favor of Uy. The Court of Appeals (CA) affirmed this award with modifications. The Supreme Court, in a Decision dated June 8, 2009, partially granted Uy's petition, ordering PEA to pay specific amounts for equipment rentals, idle manpower, and nursery shade net area, plus interest and attorney's fees. The Supreme Court's decision was subject to motions for partial reconsideration by Uy and for reconsideration by PEA. The Petition: Uy sought partial reconsideration of the Supreme Court's Decision, arguing errors in the computation of standby equipment costs, claiming entitlement to reimbursement for additional hauling distance and mobilization of water trucks, and seeking the lifting of an injunction related to claims in a separate CIAC case. PEA, on the other hand, moved for reconsideration, asserting that the Court's decision transgressed the principle of res judicata, as Uy's claims had allegedly been passed upon in a prior Supreme Court case (G.R. Nos. 147933-34).
Issue(s)
Whether the Supreme Court erred in the computation of standby equipment costs. Whether petitioner Uy should be reimbursed for costs incurred for additional hauling distance of topsoil and mobilization of water trucks. Whether the injunction preventing petitioner Uy from recovering claims in CIAC Case No. 03-2001 should be lifted. Whether the Supreme Court's decision transgressed the principle of res judicata.
Ruling
The Supreme Court PARTIALLY GRANTED Uy's Motion for Partial Reconsideration and DENIED PEA's Motion for Reconsideration with FINALITY. The Decision dated June 8, 2009, was AFFIRMED with MODIFICATION as to the award of standby equipment cost. The case was REMANDED to the Construction Industry Arbitration Commission (CIAC) solely for the purpose of computing the exact amount of standby equipment cost pursuant to the formula specified in the Resolution. The CIAC was directed to compute the award and effect payment thereof within thirty (30) days from receipt of the records.
Ratio Decidendi
On the computation of standby equipment costs: The Court found Uy's argument regarding the computation of standby equipment costs meritorious. It agreed that the actual number of equipment mobilized and on standby should be included in the computation, modifying the formula to: Actual period of delay (18.2 months) x average rate per ACEL x number of equipment. However, the Court noted that not all equipment were operational, and thus remanded the case to the CIAC for proper computation based on the specified formula and the actual number of operational equipment. On claims for additional hauling distance and mobilization of water trucks: The Court maintained its ruling that a written approval from PEA's general manager was indispensable for claims of additional costs. Since these costs were incurred without such written approval, the denial of Uy's claims was deemed appropriate. The Court stressed that the principle of unjust enrichment cannot be invoked by a party who, through their own omission, failed to secure prior notice and written consent for additional costs as required by law and contract. On lifting the injunction in CIAC Case No. 03-2001: The Court found no cogent reason to lift the injunction. It reiterated that the claims in CIAC Case No. 03-2001 were not separate and distinct from those in CIAC Case No. 02-2000, as both stemmed from the violation of the same landscaping agreement. The Court emphasized that a party cannot escape the effects of res judicata by varying the form of action or introducing new arguments if the facts and cause of action remain the same and could have been pleaded in the prior action. On the issue of res judicata raised by PEA: The Court found PEA's argument specious. It clarified that its previous Decision in G.R. Nos. 147933-34 was explicitly stated to be independent of and without prejudice to Uy's appeal in G.R. Nos. 147925-26. The prior decision was limited to the arbitral awards granted and the denial of PEA's counterclaims, and did not affect other claims of Uy not granted by the CIAC, thus not barring the grant of additional awards in the present case.
Main Doctrine
The Supreme Court, in resolving motions for reconsideration, reiterated that claims for additional costs in construction projects necessitate prior written consent from the contracting agency's authorized representative, as stipulated in the contract. Failure to obtain such consent, even if the additional work is indispensable, bars recovery based on unjust enrichment. The Court also affirmed the principle of res judicata, emphasizing that parties cannot escape its effects by merely varying the form of action or introducing new arguments if the core cause of action and facts remain the same as those previously adjudicated.
